SYLVANUS D. LOGKE, OF HOOSICK FALLS, NEW YORK.

IMPROVEMENT m GRAIN-BINDERS.

Specification forming part of Letters Patent No. 135,826, dated February11, 1873.

To all whom it may concern:

Be it known that I, SYLVANUS D. LOGKE, of Hoosick Falls, in the countyof Rensselaer and State of New York, have invented a new and usefulImprovement in Knotting-Hooks for Grain-Binders; and I do hereby declarethe following to be a full, clear, and exact description of the same,reference being had to the accompanying drawing, in which- Figure 1 is aside elevation of my device as mounted and in operative position. Fig. 2is an end elevation of the same. Fig. 3 is a front view of theknotting-hook, looking directly into the jaws thereof. Fig. 5 is a sideview of the.

same. Figs. 4, 5, 6, 7, 8, 9,10, ll-represent the hook in diiferentpositions, showing the successive stages of the process of tying theknot. Fig. 12 exhibits the cord as it is around a sheaf and knotted.

This improvement relates to the invention for which Letters Patent weregranted to me December 19,1865, No. 51,600, to which reference is herebymade for a more particular description of its generalconstruction andmode of operation. In the knotting-hook described and claimed in my saidpatent the cord is retained between the rigid jaws of the hook by aspring-latch, which, being necessarily slight,

is liable to derangement.

My present improvement consists in forming one of the jaws of theknottinghook with a permanent retaining-shoulder, projecting into aninterior -concav ity in the other jaw of said hook, with a sufficientintermediate space to permit the passage of the cord, whereby said cordmay be easily drawn into said jaw, but will be retained therein withoutwedgin g and without any springs or joints. Inthe drawing said shoulderis shown as a part of the upper aw.

That others may fully understand my improvement, I will particularlydescribe it. y ,A is the knotting-hook, mountedat the end of the shortshafta, which revolves in a box at the top of a standard, 0. Motion istransmitted to said shaft ab'y means of a pulley or cog-wheel, B, ingear with the prime mover,

and keyed fast tosaid shaft on, or in any other suitable manner. D isthe base-plate or part 7 0f the frame of the machine upon which thebinder is located. e is the permanent shoulder, and f the concavity inthe lower jaw.

In Fig. l thehook A is represented in position to receive thebinding-cord. The shield F prevents the cord 0 d from entering the jawsb bin the first instance, and causesit to be laid obliquely across theneck of the hook, as shown in Figs. 4 and 5, when a half revolution ofthe said hook causes the said cord to be wound once around the neck ofthe hook, as shown in Fig. 6.

Fig. 7 shows the hook and cord at threefourths of a revolution, the cordbeing just about to enter the jaws b b. r

Fig. 8 represents the cord and hook at the termination of onerevolution, at which time, as it will be perceived, a complete loop hasbeen formed around the neck of the hook, and

one part, d, of the cord is drawn through the jaws in front of saidloop, so that it is evident, if said loop should be drawn forward'ofl'the hook, the part at of the cord detained between the jaws would bedrawn through said loop, and a true knot would be formed without furtherrevolution of the hook; the severing of the cord (1 effects this result,as shown in Fig. 11.

Those parts of my apparatus by means of which the cord 0 d is carriedaround the sheaf, laid across the hook, and finally severed, are notshown, as the same do not enter into this invention.

In the above description, and in the annexed drawing, but one cord, 0 d,is represented but it'must be understood that, in practice, there aretwo cords-that is to say, the two ends or parts of the cord are broughttogether, as shown in Fig. 12, after passing around the sheaf, and aretogether operated upon by the hook A, and when released therefrom theknot shown in Fig. 12 unites the two ends of said cord.

Having described my invention, what I claim as new is- A rotating hookconstructed with two rigid jaws having a concave throat and solidretainingfshoulder, substantially as described.
